    General Product Description

    With its corrosion resistant properties, SSAB Weathering 460 minimizes the need for maintenance and corrosion-prevention treatment, contributing significantly to low maintenance costs throughout the product lifecycle.

    SSAB Weathering 460 allows for good paint adhesion. The intervals for repainting can be greatly extended compared to plain carbon steel since, if a damage to the paint layer occurs, SSAB Weathering steels has the ability to form a patina layer that minimize corrosion creepage under the paint and inhibits the formation of porous expanding rust.

    In addition to low maintenance costs, the reduced need for corrosion prevention means less use of paint and solvents, making SSAB Weathering 460 an environmentally friendly choice of steel.

    In manufacturing, the steel contributes to excellent productivity thanks to its good formability, toughness and weldability.

    The high-strength of the steel in combination with these properties makes it easier to build lighter and stronger products with increased payload for lower fuel consumption. Typical applications are containers, railway wagons and many others.

    SSAB Weathering 460 hot rolled strip meets or exceeds the requirements of S460J2W & S460K2W in EN 10025-5. Upon agreement, it can be delivered dual certified. This dual certification will enable producers of steel structures, in accordance with EN 1090, to use SSAB Weathering 460 in their CE-marked final component or structure. SSAB Weathering 460 can be adapted to meet impact properties requirements according to S460J4W & S460J5W in EN 10025-5 upon agreement.

    Dimension Range

    SSAB Weathering 460 is available in thickness 3.00-12.00 mm and width up to 1860 mm as coil, slit coil and as cut to length in length up to 12m.

                SSAB Weathering is delivered with SSAB Weathering tolerances. Narrower tolerances are available upon request.


                Thickness tolerances correspond to ⅔ of EN 10051 as default value.

                Length and Width

                Width and length tolerances according to SSAB standard which offer narrower tolerances compared to EN 10051.

                For coil and sheet with mill edge, the width tolerances are corresponding to -0/+20 mm.

                For coil and sheet with cut edge, the width tolerances are corresponding to -0/+2 mm.

                Length tolerances only apply for cut to length sheets.


                Shape tolerances according to EN 10051.


                Flatness tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051 flatness requirements.

                Flatness guarantees only apply for cut to length sheets.

                Fabrication and Other Recommendations

                SSAB Weathering 460 is not suited for applications requiring hot working or heat treatments at temperatures above 580°C, since the material then may lose its guaranteed properties.

                The weldability of SSAB Weathering 460 is good. All the conventional fusion welding methods can be used. To obtain the same corrosion resistance in the weld as in the base metal, special filler metals should be used.

                Painting of SSAB weather resistant steel is easy and will result in good paint adhesion. This can further increase the maintenance interval of the component.

                In order to ensure the uniform colour of the patina, all impurities must be cleaned from the steel surface. Organic impurities such as oil or protective greases must be removed by washing. Surface oxidation, oxides or rust can be removed by either shot-blasting or pickling. This will also accelerate the patina formation process. Shot-blasting is not recommended for thicknesses below 4 mms. The surface of clean weathering steel can be pre-patinated by allowing the surface to get wet and dry.

                For information concerning fabrication, see SSAB´s brochures on or consult Tech Support.

                Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
